Title: The Innovations of David Gransden

Introduction

David Gransden is a notable inventor based in Nepean, Canada. He has made significant contributions to the field of optical telecommunications, holding a total of 2 patents. His work focuses on developing advanced optical attenuators that enhance the performance of telecommunication systems.

Latest Patents

One of Gransden's latest patents is the Variable Optical Attenuator. This invention features a multiple-aperture design, where a thin element contains a plurality of apertures arranged in a specific pattern. The size of most apertures increases along the length of the element, allowing for a variation in the percentage of transmitted light. This design is notably independent of wavelength and polarization, making it versatile for various applications.

Another significant patent is the Voltage Controlled Attenuator. This device is designed for optical telecommunication systems and is positioned between an input and an output lens. It obstructs the path of an incoming light beam while allowing for variable attenuation, which is controlled to maintain a preset power of the outgoing light beam. A fraction of the outgoing signal is diverted to an output detector, which processes a control signal to actuate a DC motor, adjusting the attenuator's position accordingly.
